چکیده
Abstract Researchers at Texas A&M University (TAMU) have designed the radiation integrated circuit (RIC) for deployment as a new detection system. Most circuits are susceptible to radiation-induced failures, and decades of research gone into solving this problem. Research TAMU has led novel design that utilizes both radiation-hardened areas (RHAs) radiation-sensitive (RSAs) take advantage these failures. The RSAs charged particle interactions, allowing RIC detect alpha beta particles. However, particles more penetrating compared particles, resulting in lower interaction probability incident on bare RIC. In any material, higher energy, deeper can penetrate; therefore, use wedge-shaped attenuator not only increases probability, but also provides capability perform maximum energy discrimination field. objective was optimize Monte Carlo N-particle transport code (MCNP) simulations assessed performance plate glass, borosilicate (Pyrex®) acrylic (Lucite®), natural rubber attenuators. proof-of-concept analysis, observed be optimal attenuating material probe with respect weight, all materials considered proved good candidates. results study promising indicate potential achieve 50 keV using wedged,

متن کاملA Novel Analysis of Sequential Circuits Design Using Reversible Logic
Reversible logic design attracts more interest due to its low power consumption. A lot of research has been done in combinational as well as sequential design of reversible circuits. As far as it is known, this is the first attempt to apply reversible logic to synchronous counters design using T flipflop. In this paper we have also proposed a new reversible gate which can be used as copying gat...
